RPC & Indexers

RPC Providers

Citrea provides free RPC endpoints for developers to use: https://rpc.mainnet.citrea.xyz and https://rpc.testnet.citrea.xyz. For small projects & simple queries, you may use this endpoint safely as it offers generous rate limits.

However, for larger projects or production use, we recommend setting up your own RPC node or a dedicated RPC provider.

Alchemy

Alchemy is a high-performance RPC provider that offers a generous free tier and stronger paid plans for higher usage for Citrea. You may refer to their webpage for more details on the usage.

Indexers

Goldsky

Goldsky is a Web3-native, real-time data platform that lets you index and query on-chain data without wrangling infrastructure. Built for effortless scale and backed by 24 × 7 support, it frees you to ship features instead of managing servers.

Citrea supports both Goldsky Subgraphs and Goldsky Mirrors. Subgraphs provide high-performance, custom-modeled queries with smart tagging for precise filtering for your development, and Mirrors stream live blockchain events straight into your own database and keep data continuously in sync.

As a developer building on Citrea, you can utilize Goldsky products at a discount. Check out the Citrea page on their documentation for more information and kickstart your development!

Note: The correct Citrea slug for Goldsky is citrea-testnet-tangerine for testnet, and citrea for mainnet.

Envio

Envio is a super-fast data platform on Citrea with HyperIndex and HyperSync support.

Using Envio HyperIndex you can transform on-chain events into structured, queryable databases with GraphQL APIs.

Envio HyperSync is Envio's high-performance blockchain data engine that serves as a direct replacement for traditional RPCs for read-only endpoints, delivering up to 2000x faster data access.
